One of the many questions that people have been asking in regards to jailbreaking iOS 5 is whether ultrasn0w was going to be updated for iOS 5 in the coming future. Until yesterday, no one knew what the status was of ultrasn0w on iOS 5. MuscleNerd (@MuscleNerd) tweeted out yesterday however that the team was waiting to release an ultrasn0w update until a scheduled Mobile Substrate update was released (update is available now). It was only a matter of time until that time came.

The ultrasn0w Twitter feed (@ultrasn0w) just tweeted out that ultrasn0w has been updated to support iOS 5. The link in the tweet directs to the iPhone Dev-Team Blog which has a post that goes into lengthy detail on what ultrasn0w for iOS 5 is all about. Read below to get the entire post directly from the iPhone Dev-Team Blog. Please read EXTREMELY CAREFULLY:

We’ve updated ultrasn0w to be compatible with iOS5, which came out a few days ago. While ultrasn0w 1.2.4 doesn’t add support for any new basebands, the update is required for any ultrasn0w unlockers trying out iOS5 (it remains backwards compatible though, so you should be able to use it no matter what firmware you have).

The supported basebands for the iPhone 3G and 3GS are 04.26.08, 05.11.07, 05.12.01, 05.13.04, and 06.15.00. The baseband supported for the iPhone4 is 01.59.00.

Remember, the only way to get to iOS5 while preserving your ultrasn0w-compatible baseband is by using a custom IPSW. redsdn0w now has the ability to create such a custom IPSW for you (at least on Macs…the same capability for Windows will be coming soon).

The majority of people who use ultrasn0w at iOS5 right now will probably be those with old-bootrom iPhone3GS devices, since they already have an untethered jailbreak via redsn0w. For everyone else, the iOS5 jailbreak is currently tethered and you need to “Just boot” tethered with redsn0w every time your phone reboots. That’s not always easy to do if your phone reboots while away from home!

Note: there’s a special “trick” that iPhone3GS owners with baseband 06.15 need for iOS5. During the new setup screens you see when you start iOS5 for the first time, you’ll be asked about Location Services. Be sure to select “Disable Location Services” when asked! Later on in the setup, you’ll have the chance to turn on Location Services again when asked if you want to use “Find my iPhone”. It’s fine to turn it back on at that point, if that’s your desire (or you can always go in and enable it in Settings.app).

Also, some iPhone3GS users with the 06.15 baseband may have tried to install iOS5 using a stock IPSW (even though you should never ever try to use a stock IPSW if you’re an ultrasn0w unlocker). If you did try this, your baseband is probably in an inconsistent state, and you’ll need to reflash the 06.15 baseband again (using redsn0w). Be very careful if you use redsn0w to reflash the iPad baseband — don’t interrupt the process1 And please avoid using stock IPSWs in the future Unlockers should never go near stock IPSWs.

If you need to use redsn0w for any of the above tasks, please make sure it’s version 0.9.9b4 or higher, which is available here.

Enjoy!

Here's what to take away from this update on ultrasn0w:

The supported basebands for the iPhone 3G/3GS are 04.26.08, 05.11.07, 05.12.01, 05.13.04, and 06.15.00

The baseband supported for the iPhone 4 is 01.59.00

The only way to get to iOS 5 while preserving the ultrasn0w-compatible baseband is by using a custom IPSW (redsn0w 0.9.9b5 currently only supports Mac (Windows coming soon - Windows users use sn0wbreeze v2.8 beta 8 at this time)

The iOS 5 jailbreak is still tethered except for iPhone 3GS old bootrom users

iPhone 3GS users with the baseband 06.15.00 need to make sure to do the special trick as mentioned in the post

Unlockers should never go near stock IPSWS

NOTE: This ultrasn0w update only supports existing basebands. There is no new unlock at this time.

Can someone please tell me the difference between the sn0ws? I've been jailbreaking since 3.x and I've always wondered. I've never had to use either redsn0w or ultrasn0w because there's always been geohot's one button jailbreak or the jailbreakme. I used redsn0w for my current tethered jailbreak on 5.0. Anyways, I'd like some clarification.

Tl;dr: what is a "sn0w", and what's the difference between red and ultra and any other colors?

Redsn0w is a jailbreak program to jailbreak an iPhone (put cydia on ur springboard).
Ultrasn0w is sub program (within cydia) that unlocks the iPhone 4 with a rare baseband 01.59.00 only! as it also supports other rare 3GS basebands specifically noted. Ultrasn0w also unlocks the original iPhone and iPhone 3G without a hitch!

Any other sn0w colors r considered userland jailbreaks by people that created a jailbreak to put cydia on there springboard and some are very good ideas.

Tethered jailbreaks r a hassle because depending on the tweaks or cool cydia apps u may need to reboot and lose the jailbreak and/or more.
Untether jailbreaks r preferred as it doesn't require a computer to reboot in case ur phone needs to be powered off.

Now all we need is some untethered action! I'm chomping at the bit to jump onto iOS 5..

I'm pretty sure redsn0w is just the predecessor to ultrasn0w. They are used for unlocking the devices, not the jailbreak process. I could be wrong, but that's what I have gathered.

^^ yup. I was wrong haha. I knew ultrasn0w was unlocking but I have never used redsn0w. I have always used pwnage tool to preserve the baseband in case I ever needed an unlock, but now redsn0w can do that as well. I was confusing myself as I was trying to explain it.

redsn0w is a jb tool, just like geohotz's jailbreakme.com
ultrasn0w an unlocking tool, for people who want to use a non-original carrier
sn0wbreeze is also a jb tool, just like redsn0w but for windows, red is for mac

redsn0w is a jb tool, just like geohotz's jailbreakme.com

hope that clarifies it

pretty sure geohot's work was all in the form of ra1n, jailbreakme.com was comex.
